Is the new database also 7.4? Why not 8.1 oder 8.2?

IIRC a know issue with 7.x, but solved (i hope...) in 8.x. If you
upgrade to such a version, you should use the pg_dump(all) from this
against the old database.

You can use pg_restore with -l to generate a listfile for all objects in
the database. Then you can reorder this ($EDITOR) and then use -L to use
this ordered listfile to enforce the right order of objects. I hope this
helps you.
(man pg_restore)
